Quote of the day by David Swensen: "The underlying driving force behind market timing decisions seems to be emotional — fear, greed, chasing performance — buying something after it has gone up, disappointment, and sales after something has declined."

David Swensen emphasizes that emotional biases, such as fear, greed, and performance chasing, often drive poor market timing decisions. Investors should rely on disciplined, long-term strategies and focus on controlling their responses rather than predicting market movements.
